We argue that if gravitational interactions play an important role in the amplification and transfer of turbulent energy between sub-clouds of different scales in a GMC, then the Second Law of Thermodynamics requires that the transfer occur from smaller to larger scales, and hence that the seed-energy be injected on relatively small scales.
